Hello, I have a question : a lexer does exist for Postscript for Scintilla (LexPS.cpp in the scintilla src). My question is : how to create a qscilexer for postscript as it exists for Tex, CPP (More generally, there are much more lexer than QsciLexer. How to port a scintilla lexer to Qt4 ?) Thank you for your help Gwenael
